WINDOW-FASTEN ER.

srncricnrion forming para of Letters ratei@ Ns. 629,446, dated July 25, 1899.

Application filed February 9, 1899.

To all whom, t may concern Beit known that l, WILL S. JAMES, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, 5,have invented a new and usefulvWindow- Fastener, of which the following is a specification.

The invention relates to improvements in window-fasteners. v

The object of the present invention is to improve the construction of window-fasteners and to provide a simple, inexpensive, and efficient device adapted for holding a sash at the desired adjustment and capable of being i readily arranged to lock the same against upward or downward movement.

A further object of the invention is to provide for sashes having no counterbalancingweights a device which will enable a sash to 2o be raised freely, but which will prevent the same from dropping or moving downward.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation, partly in section, of a portion of a window provided with a device constructed in accordance with this invention. Fig. 2 is a perspective view of the locking device, the spring- .actuated bolt being arranged to present upper and lower shoulders. Fig. 3 is a longitudinal sectional view of the same.

5 5 a detail perspective view of the casing, showing the rear face thereof., Fig. 5 is an eleva-l tion, partly in section, illustrating the modi# tication of the invention. Fig. 6 is a transverse sectional view of the locking device 4o thereof.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a ratchet-strip constructed of suitable metal and provided at intervals with rectangular bends 2, forming upper and lower shoulders, which are adapted to be engaged by a spring-actu ated bolt 3, and the said strip is secured to a window frame or casing adja- 5o cent to a sash by screws or other suitable fastening devices passing through perforations formed in the angular bends 2 and arranged Fig. 4is- Serial No. 705,057. (No model.)

at intervals. The spring-actuated bolt 3, which is provided with a beveled engaging end4, is arranged within a casing 5 and is provided adjacent to its engaging end with a lug or projection 6, preferably cast integral with the bolt and operating in front and rear slots 7 and 8 of the casing 5. The inner por# tion of the bolt is reduced to receive a coiled spring, which bears against the shoulder formed by reducing the bolt and which en; gages the inner end of the casing, the latter being provided at that point with an interior shoulder formed by reducing the bore. p

The front slot, which communicates with the bore, extends inward from one end of the casing', and the rear slot terminates short of such end of the casing and is provided at its inner end with oppositely-disposed branches 9 and 10, the former communicating with the front slot at the inner end thereof 'and permitting the lug or projection to be transferred from one slot to the other by partially rotating the bolt. This construction enables the bolt to be given a quarterturn to arrange its beveled edge uppermost, as shown in Fig. 1, or to arrange its iiat side edges in a horizontal position to engage the shoulders of the ratchet-strip for locking the sash against upward or downward movement. The other branch 10 of the inner'slot forms a stop and is adapted to be engaged by the lug or projection to hold the bolt retracted and out of engagement with the ratchet-strip, so that the sash may be moved freely in either direction. The slots also form convenient means for enabling the part-s of the locking device to be readily assembled, and the inner end of the bolt is threaded at 11 and receives a detachable head 12, having a threaded opening and normally holding the bolt sufficiently retracted to retain the lug in the grooves and prevent the same from leaving the front slot. In Figs. 5 and 6 is illustrated a modification of the invention, in which a round bolt 13 is employed, and this round bolt is adapted to engage perforations la of a ratchet-strip l5, which is provided at intervals with rectangular bends. The casing 16, which receives the bolt 13, is constructed similar to the casing heretofore described, and it is provided with front and rear slots to enable the parts to be assembled.

'IOO

The form illustrated in Figs.l1

to 4, inclusive, is especially adapted for sashes having no counterbalanGing-weights, and the other form is adapted for balance-sashes.

The invention has the following advantages: The window-fastener, which is simple and comparatively inexpensive in construction, is adapted to be readily applied to upper and lower sashes whetherweighted o r unbalanced. It is adapted to support a sash at the desired elevation, and it is capable of locking it against upward or downward movement.

The spring-actuated bolt may be retained out' of engagement with the ratchet-strip to enable the sashes of a window to move freely in either direction, and when itis disposed with its beveled edge uppermost the sound caused by the bolt riding over the shoulders will be sufficient to alarm the inmates of a room should any one attempt to raise the sash from the exterior. The slots at the front and back of the bolt-casing permit the parts to be readily assembled and separated.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to Without departing from the spirit orsacriicing any of the advantages of this invention.

Whatvis claimed is- 1. A device of the class described comprising a casing having a bore and, provided at opposite sides with longitudinal slots, one of the slots being extended to one end of the easing t0 form an entrance and the other slot being provided at its inner end with a branch communicating with the entrance-slot, and a detachable bolt adapted to engage a ratchetstrip and provided with a lugarranged t0 enter the said slots, substantially as described.

:2. A device of the class described comprising a casing having a bore and provided at opposite sides with longitudinal slots, one of the slots being extended to one end of the casing to provide an entrance, andthe other slot being provided at its inner end with opposite branches communicating with the entranceslot and forming a stop, and a detachable bolt adapted to engage a ratchet-strip and provided with a lug arranged to operate in the said slots, substantially as described.

3. Adeviceof the class described comprising a casing having a bore and provided with oppositelongitudinalslots and havingatransverse branch located at theinnerends of the slots, and a beveled bolt provided with a projection or lug located at a point between its ends and operating in the said slots, whereby the bolt is adapted to be partially rotated, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signaturein the presence of two witnesses.
